Annplt 81

ANNPLT-81:
- Adding portlet preference for all the tiny mce textbox intitialization options
- Removing "Path: <item(s)>" from create and edit announcement textbox bottom border by default in the new portlet preference
- Adding default value in both portlet.xml and controller
- Changing tabs to spaces in controller and jsp
- jsp had html commenting out the mce init within the javascript.  This didn't serve a purpose, was confusing to look at and was removed
